Abstract
"COMPOSIçãO AMBIENTALMENTE DEGRADáVEL, SACO, ENVOLTóRIO, LAMINADO DE MúLTIPLAS CAMADAS, BEM COMO PELìCULA DO REFERIDO LAMINADO E PELìCULA AMBIENTALMENTE DEGRADáVEL". A presente invenção refere-se a películas ambientalmente degradáveis que contêm uma mistura de copolímero de poliidroxialcanoato e um polímero ou copolímero de ácido polilático. Ela também refere-se a laminados que têm uma primeira camada que contém um copolímero de PHA e uma segunda camada que contém um polímero ou copolímero de PLA. Artigos descartáveis que compreendem as películas ou laminados ambientalmente degradáveis também são descritos."ENVIRONMENTALLY DEGRADABLE COMPOSITION, BAG, WRAPPING, MULTI-LAYER LAYER AS WELL AS FILM FROM THE REFERRED LAMINATE AND ENVIRONMENTALLY DEGRADABLE FILM". The present invention relates to environmentally degradable films containing a mixture of polyhydroxyalkanoate copolymer and a polylactic acid polymer or copolymer. It also refers to laminates having a first layer containing a PHA copolymer and a second layer containing a PLA polymer or copolymer. Disposable articles comprising environmentally degradable films or laminates are also described.
